In this talk, I will review recent observational efforts that begin to shed light on how molecular clumps collapse and fragment to form high-mass stars and protostellar clusters. I will highlight thermodynamic properties of dense cores that appear to challenge the long held notion of equilibrium star formation. And finally, I will present observational evidence that is critical to the formation of the most massive stars in galaxies.
